From e015fca097484be6d2616d1e9d5aae89b0937ce8 Mon Sep 17 00:00:00 2001 From: Hyong Youb Kim Date: Wed, 30 Oct 2019 22:36:22 -0700 Subject: [PATCH] net/enic: fix speed capabilities for new VF VFs all have subsystem ID 0. VIC models with the latest VF are at least 40G, so report that as a more reasonable speed than 10G.
